Description of key information

The measured partition co-efficient for 97280-83-6  was reported to be 7.6 to 7.8 (Log Pow). Estimated log Kow for the butylene oligomers ranged from 4.12 - 9.91

Key value for chemical safety assessment

at the temperature of:
20 °C

Additional information

A guideline proprietary study (Evonik Oxeno 2009) for 97280-83-6 found log Pow to be 7.6 to 7.8. The value of 7.8 will be used for the partition coefficient as it is most conservative. QSAR (KOWWIN in EPISuite V4.1) estimated the log Kow for the butylene oligomers to range from 4.12 - 9.91
